I think it is the Star Ferry Pier on Connaught Road. There appears to be a ramp that leads off to the right for first class passengers. If one looks directly out to the main entrance, there is a conical traffic control post in the middle of the road. The structure can be seen below.

Good morning Peter and Moddsey. Thank you for your thoughts. I think that the wooden roof structure does not match my recollection of the Peak Tram building, which was a modern concrete building, so the old Star Ferry pier is my candidate. Enlarging the area beneath the Hueur sign I think I can just make out a road, Ice House Street(?), with a car parked on it, that is more or less opposite what looks like the entrance. That would fit better with the ferry pier. Any more contributions? Best wishes, Andrew
